These all contributed to the rapid computer networking technology of large-scale use. As we all know, the worlds largest information network use of, Internet openness of their agreement greatly facilitate a variety of computer networking to broaden the sharing of resources. However, in the early design of network protocols on security issues of neglect, as well as in management and use of the anarchy, the Internet increasingly serious threat to their security, and its related security incidents happened quite frequently. Network security threats mainly in: unauthorized access, posing as legitimate users, damage to data integrity, interfere with the normal operation of the system, using the Internet spread the virus, line tapping and so on.Therefore, this paper for the enterprise (Hong Jin corporate network) architecture network security system, mainly by the use of vlan, firewall, vpn, virus protection and other technologies to achieve corporate network security. Keywords: network, security, VPN, firewall, anti-virus 目 录 绪 论 1 第一章 企业网络安全概述 2 1.1 企业网络地主要安全隐患 2 1.2 企业网络地安全误区
